Abstract

Indonesia aims to achieve a 23% utilization of new renewable energy (EBT) by 2025. This form of clean and sustainable energy derives from sources such as solar, water, mini/microhydro, geothermal, and bioenergy, all of which have minimal to no environmental impact. The Provincial Government of Bali has introduced a directive to promote the adoption of EBT. The choice of the Bali Provincial Governor's Office for this initiative stems from its significant electricity consumption and its potential to serve as a model for photovoltaic solar (PLTS) development in Bali.This study delves into the conceptualization of a PLTS system installed atop the Bali Provincial Governor's residence. The design process involves determining the appropriate quantity of solar panels for the roof, evaluating the potential electrical output of the PLTS, selecting the specific PLTS model and inverter for implementation. To aid in this endeavor, the Helioscope software is employed, aiding in the visualization of the PLTS layout and its potential energy generation.Four distinct scenarios were considered in this study: In Scenario 1, a configuration employing 114 solar modules with a total capacity of 63.7 kWp is proposed, utilizing a single inverter with a capacity of 66 kW. Scenario 2 adopts a setup with 64 solar modules, yielding 35.3 kWp in capacity, coupled with a single inverter boasting 36 kW capacity. Scenario 3 envisions the installation of 142 solar modules generating 78.1 kWp, harmonized with a lone 80 kW inverter. Lastly, Scenario 4 opts for 64 solar modules producing 35.3 kWp, each equipped with 22 microinverters with a capacity of 2000 Watt.

Abstract

Yeh Ha River in Ababi Village, Karangasem Regency, Bali, is a river that originates from the Yeh Ha springs and is used as a bathing place. This river has the potential for a new renewable energy source that can be utilized for the Micro Hydro Power Plant (MHPP). Discharge measurements were carried out for a week on one of the Yeh Ha spring source channels during the dry season. The results showed an average discharge of 0.201 m3/s. The discharge data used is the minimum potential energy that can be absorbed. Based on the measured discharge data and the used head of 4.6 m, the Tanaka Suiryoku Turbine Selection Chart shows that the crossflow turbine meets the turbine selection criteria. The results of the analysis and calculations show that the available power at the turbine is 8 kW with an efficiency of 80%. A 3-phase synchronous generator with a permanent magnet rotor was selected based on a comparison of the types, specifications, and characteristics of the generator to match the turbine capacity. The output power generated by the generator is 6 kW with a rotational speed of 1500 rpm and a generator efficiency of 90%.

Abstract

The development of modern automotive technology emphasizes the importance of vehicle connectivity and autonomy, with the aim of enhancing safety and comfort. Due to its role in managing critical vehicle functions and its vulnerability to security threats, the automotive industry has developed two primary approaches to address CAN Bus security. Therefore, the automotive industry has developed two main approaches to address this security issue. First, passive defense through security protocols that include encryption, authentication, and message verification, and second, anomaly detection using advanced technologies. Several anomaly detection methods have been introduced, including K-Means clustering, Support Vector Machines, and Deep Learning, each offering advantages in detecting specific attack patterns. However, one increasingly popular approach is time analysis, which leverages message inter-arrival patterns and clock skew on the CAN Bus to identify suspicious behavior and detect anomalies in real-time. Although this method has shown effectiveness in detecting various types of attacks, the main challenge lies in its ability to identify highly concealed attacks that may not be visible to traditional methods. This research provides an understanding of various anomaly detection approaches on electric vehicle CAN Bus networks, with a primary focus on time analysis. By reviewing several approaches, this study offers valuable insights into improving the security of electric vehicles and the overall smart transportation ecosystem. The results show that time-based analysis methods can detect various types of attacks, such as spoofing, replay attacks, and denial-of-service, with high efficiency.
